ALBERT J. B. HAR'RS ANB RAYMOND S. H'MBURGH, OF ROCHESTER, NEW YORK.

DOOR 'LOGI/UNG AND OFERATING 'EdEC-IANISM.

Application led July 6, 1915.

To all 'whom i 'may concern:

Be it known that wegliiiinfr J. B. vHAR- icis and RAYMOND S. HUMBURCU, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a certain new and useful linprovernent in Door Locking and 4Operating Mechanism, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in door locking and operating mechanism.

An object ot the invention is to provide simple and elicient means for securely closing and positively opening a slidable door, in combination with improved means for sealing the door operating mechanism.

Another object of the invention is to provide a door closing and opening mechanism, more particularly adapted for box car doors; said mechanism including a pivoted lever mounted on the door, and which cooperates with a keeper secured to a door post, the keeper andlever having coperating camming suriacesso arranged that in swinging the lever in one direction the door will be movedto fully closed position, and when the lever is turned in the opposite direction the door will be positively forced open. p In the drawing forming a part of the specification, Figure 1 is a side elevation o1 a portion oi a box car, showing our iniproveinent in connection therewith. Fig. 2

is a side elevation upon an enlarged scale,

showing more particularly the door operating mechanism and sealing arrangement, the

dotted lines indicating the position ofV the zcntal sectional view, taken on the line 3-3 of Fig. 2. Fig. Il is a detail sectional view, taken on the line 4-4 of :Fig 2, arid Fig. 5 is a vertical sectional view upon an enlarged scale, taken on the line 5-5 of Fig. 2.

ln said drawing, denotes the car having door post 11, and a sheetsteel slidable door 12, mounted on suitable track 13. On the outside of the post 11 is secured a substantially Z shape strip 14, adapted to form. a stop and weather protector for the edge of the door.- The door i12 is provided with. a channel shaped stri 15 on its outer side near the front edge t ereof, and to the latter are riveted two L shaped castings 16 and 17,

Serial No. 38,112.

the former being on the interiorand the latter on the exterior, said castipgs 16-17 bracing the strip 15 in order tot'torm a suitable support for the pivoted lever aboutpto sie be described.

r1`hc improved operating mechanism, as shown, consists of a lever 18, pivoted as at i 19, to the castings 16 and 17 on/the door;

and a keeper 2O secured to the'door post. 65

The keeper 20 is in the forni of a cast bracket having an offset double faced cani .21. rlfhe cam 21 has its upper face orcainming surface 22 arranged eccentrically to the pivot 19 of the lever 18.. The lever 18 '70 is provided with a hook shaped portion 23, having a curved camining surface 24, arranged preferably concentrically with the pivot pin 19, and which is adapted to cooperate with the cannning surface 22. The

of the member 21, as hereinafter described. The lever 18 has pivotally connected therewith, a handle 27, it being observed that the aXis of the pivotal connection between the lever 18 and the handle 27 extends at vright angles to the axis of the pivot 19, whereby the handle 27 may be swung toward and from the door 12.

The operation in closing and opening the .door is, as follows: I

Assuming the door to have been moved substantially to closed position, and the lever and handle in the position indicated by dotted lines in Fig. 2, the lever and handle are then swung counter-clockwise, so that the camming surface 24 of the lever engages 95 the eccentrically arranged camining surface 22 oi the keeper. As will be understood, this will pull the door tight' against the stop, the lever Zontal position, this condition will be maintained. To open the door the lever and handie are swung downwardly'or clockwise,

whereupon the oamming surface 25 willengage the camining surface 26 of the keeper 105` and positively force the door part way open.

To hold the lever and handle in proper position when the door is closed, we have provided an improved sealing arrangement, designated generally by the reference B. As

shown, this consists of a castingl 28, riveted to the door, and having an outwardly exrateatea .nay-3,' ieiv.

and the arrangement is such that if 18 and handle 27 are held in horiyl' l cess in the staple 29. Preferably, the pivotal connection' for the lock member 30 is' arranged, as indicated at 33 in Fig. 5, and coincides with one oi' the rivets for securing the casting 28, it being understood that a suitable bushing and @acing arrangement is provided to prevent binding of the mem, ber 30. The hook shaped section 31 of the lock 30 is provided with alined perforations, in which is adapted to be received, a Seal pin 34, having an elongated slot 35, te permit the seal pin to slide up and down on the headedrivet 36, secured to the top of the lock member 30, The handle 27, as clearly shown -in Figs. 2 and 3, is I rovided with a. slot 37, to thereby permit t e handle to be swung over the staple 29.

The sealing arrangement is shown in the.

drawing in t 1e condition it would be when the door is closed and the car sealed. To release the handle 27, the sealing wire (not shown) which lis adapted to be passed through the slot 38 in the lower end of the pin 34 is first removed, then the pin 34e. is lifted so as to withdraw from the Staple 29, then the lock member 30 is swung about its pivot 33, whereupon the handle 27 ma7 be swung outwardly, as indicated in dotted lines in Fig. 3.

Although we have herein shown and described what we now consider the preferred embodiment of our invention, the same is merely illustrative, and we contemplate all changes and modifications as come within the scope of the claims appended hereto.

We claim:

1. The combination with a member having a door opening, and a slidably mounted door for closing said opening, of a keeper mounted on said member having fixed opening and closing camming surfaces, a lever mounted. on said doeil and pivoted about an axis perpendicular to the face of the door, said lever having a hook shaped end on one side of its pivot, said end being provided with two opposed camming snriaees an ranged to coperate with said cammlng sur Jraces on the keeper, said lever having also a handle on the opposite side of said pivot,

and closinfy camming surfaces, a lever pivoted to said door near its front edge, said lever having a hook shaped end provided with camming surfaces coperable with said eamming surfaces of the keeper, said lever being oscillatable in a plane parallel. to the face of the door, said lever having also an operating handle pivotally connected thereu to, a staple secured to the door, said handle being slotted to thereby permit it to be positioned over the staple, a lock pivotally mounted on said door and adapted to swing in a plane parallel to the 'aee of the door, and a seal pin slidabl)T mounted on said loclrv and adapted to extend through said staple and secure handle in locked position.

3. In mechanism of the character described, the combination with a member hav-3 ing a door opening and a slidable door for closing said opening, of a keeper mounted on said member, a lever pivotally mounted on said' door, said lever being provided with' a slotted operating handle, a casting secured, to said door, said casting having a staple over which said slotted handle is adapted to be positioned, a lock pivotally mounted on said casting and adapted to swing in a plane parallel to the face of the door, said lock having a portion adapted to i'it over the outer end of said staple, and a seal pin slidably mounted on said lock by means of a pin and slot arrangement.

In witness that we claim the foregoing we day of June, w15. f
